Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65500, here are decompositions:
- 3 + 65497 = 65500
- 53 + 65447 = 65500
- 107 + 65393 = 65500
- 173 + 65327 = 65500
- 191 + 65309 = 65500
- 233 + 65267 = 65500
- 317 + 65183 = 65500
- 353 + 65147 = 65500
Showing the first eight; more decompositions exist.
